-.\hi -h the following is u speril'iration.

This invention relates to the production of the so caller j lime and sulfur solution and purliculnrly,to n novel process for its manufacture. 4 I

.x-in important object of this invention is to provide :1 novel process to produce lime and sulfur solution, whereby the manufacture is rendered expeditious and continuous, and the cost redilcecl by economizing in the use of sulfur.

other objects and advantages of this invention will be apparent during the course of the following (lest-ri 'ition.

in the ueconipunying drawing forming a. part oi this specification and in which reference irluu'uoters are employed to designate parts throughout the same, the figure is a side elevation, partly in sect-ion, of an apparatus, suitable folcarrying out myprocess.

in the ordinary process of making lime and sulfur solution, slnkecl lime is mixed with powdered sulfur and a suitable amount of water. The mass is heated until the lime combines with the sulfur, and the water dissolves this product, forming lime and sulfur solution." lhis process cannot be carried on profitably, owing to the large percentage of sulfur that is wasted. 'lhe sulfur is generally used in excess and being powdered, such excess is lost through min ture with. the insoluble lime and sulfur compounds which form at the some time with These insoluble compounds have no value and form a mess \\lll(l1 lll1lSiZ:

the solution.

beremoved and hence the loss of the excess of sulfur forming a port of it.

In my present process, just the correct uineunt of sulfur is made to combine with a certniii amount of lime, by cu'iploying the sulfur in. excess in the Form of large lumps, placing it in Contact with the lime, and subjecting the mass to the action of water. By heutingthis muss in the presence of mois ture, .the exterior of the lumps of sulfur,

with it,f'w,herehy utter the lime has entered intoeomhfnutiomlhe excess of sulfur still remains."i ;ri the lump form and may be treated with a further amount of lio water is circulated about the lump sulfur and lime, to dissolve and tulae into solution the combined lime uiul sullur, thus forming lune sulrur solution."

Reference heing had to the droning. designates a vertically disposed recep'twle or shell for holding; the lurg lumps sulfur and lime. This receptm has its upper end formed open and the lower portion of its periphery provided. with perforations 2. The shell I is supported con centrioully in an outer cylindrieu shell or casing 3 by legs Cl, as shown. The bottom of the receptacle 1 is spaced from the hottunii. of the shell t The numeral designates a rotary prune of any well knimn-or preferred type, Wl'iich has communication with the lower end of the outer shell or casing 3, through u re turn pipe (5. AL supply pipe 7 hue communication with the feed end of the pump 5 m" extends upwardly to discharge into the ceptucle or shell 1. The supply pipe provided with a valve 8. r-i discharge gtiioe 9 has connection with the pipe "Z new: l pump 5 and {a valve 10 is "girovided-iu the pipe 9. I provide heating means in the term 0 steam coil 12, which surrounds the re tacle or shell 1, as shown, li-ieuinis su plied into this coil at its roper end oil- 1 discharged from the lower end thereof.

In carrying out my process, lerge lumps of sulfur are fed. into the reoepiiucle Li and. a comparatively small ninount oi is introduced into the recegitnole to the lump sulfur; The vnlves 8 on. now opened to supply water from t. 9, through pipe '1, into the upper end oi: receptacle.

Mir u lir'ne. Heat, is then epplie to the receptors to raise the temperature of the sulfur lime to about Q. to aid in. the combining of the sulfur and lime, The lime in ha Ei nutter percolating through the lump sulfur and lime dissolves the combined lime and sulfur, forming the lime and sulfur solution After all the combined lime and sulfur has gone into solution, the valve 8 is closed, valve 10 opened, and the pump operated to discharge the lime and sulfur solution into a suitable receptacle (not shown) through pipe 9.

' I wish it understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes may be made therein without departing from the spirit of the invention or'the scope of the subjoined claims.

Having thus described my invention, I claim 1. lhe herein described process which con sists in subjecting lump sulfur to the action of lime, and circulating water through the mass to dissolve the combined sulfur and lime, n'hile heating the mass.

2. The herein described process which consists in holding lump sulfurand nine in contact, preventing the escape of the lump sulfur while causing water to percolate through the mass, which is simultaneously subjected to theaction of heat.

3. Tim herein described process, which consists in placing lump sulfur and lime in a receptacle provided with perforations too fine to permit the lump sulfur to pass tirough, and flowing water through the mass It! the reee tacle to dissolve the combined sulfur an lime, while heating the snass.

4. The herein described process which c sists in placing a relatively small amount of lime with lump sulfur, causing water to circulate through the mass for a number of times, and simultaneously subjecting the mass to the action of heat.

5 The herein described process, which consists in heating lump sulfur while sub jccting it to the action of a solution of lime in water, for causing all of the lime to com' bine with a portion of the lump sulfur and leaving the excess of sulfur in the lump form.

6. The herein described process, which consists in heating a mass comprising lump sulfur in excess and lime, while subjecting it to the action of water, for causing all of the lime to combine with a portion of. the lump sulfur and leaving the excess of sulfur in the lump form.

7. The herein described process, which consists in heating a mass comprising lump sulfur in excess and lime, while subjecting it to the action of circulating water, for causing all of the lime to combine with a portion of the lump sulfur and leaving the excess of sulfur in the lump form, and Withdrawing the lime and sulfur solution obtained.

8. The herein-described process which consists in placing lump sulfur and lime in a receptacle provided with perforations too fine to permit the lump sulfur to pass through, causing water to percolate through the mass, and simultapeously subjecting the mass to heat.

In testimony whereof I afiix my signature in presence of two witnesses.
